How long are the narrow skeletal muscle fibers in your body?
Up to 1.5 inches
Fascia extends beyond the muscle to form a ______, which attaches to a bone’s periosteum at the origin and insertion of the muscle.
Tendon
Striations
Alternating dark and light bands of protein filaments responsible for muscle contraction

What does RICE stand for?
Rest, ice, compression, and elevation
Muscle soreness
Results from vigorous exercise, particularly if your muscles are not used to it. Exercise increases the lactic acid in your muscle fibers, causing inflammation, and produces soreness in the muscles and nearby connective tissue.
Muscle cramps
Sudden, short, painful contractions of a muscle or group of muscles. The cause of the cramps is unknown, but a poor diet that leads to low blood potassium, calcium, and magnesium levels; caffeine and tobacco use; and reduced blood supply may contribute to muscle cramps.
Muscle strains
Can be a simple stretch to a partial or complete tear in the muscle, tendon, or muscle-tendon combination. Most healed with RICE, followed by basic exercises to relieve pain and restore mobility, but a complete tear may require surgery.
Anabolic steroids
Related to testosterone but altered to make skeletal muscle hypertrophy; used illegally in many sports to boost muscle strength, steroids have noticeable, often irreversible side effects
What are the irreversible side effects of taking anabolic steroids?
Stunted growth in adolescents, shrinking testes and reduced sperm counts, masculinization of women’s bodies and voices, delusions, and paranoid jealousy. Long-term effects may be increased risk of heart attack and stroke, kidney failure, and liver tumors.
What is the treatment for fibromyalgia?
